Abstract
Systems and methods for investigating and addressing excessive battery drainage in a wireless device in a cellular communications system are disclosed. In some embodiments, a method in a core network of a cellular communications system comprises receiving, from an external entity, a request to investigate excessive battery drainage at a particular wireless device and initiating collection of information related to operation of the wireless device. The information comprises user plane data, control plane information, and/or network information related to the wireless device. The method also comprises collecting the information from one or more network nodes in the cellular communications system, analyzing the collected information to determine one or more root causes of excessive battery drainage at the wireless device, and initiating one or more actions in the cellular communications system to mitigate excessive battery drainage at the wireless device.
